IMPROVEMENT IN DEVICES FOR RELEASING HORSES FROM STALLS.

PATENT QFFIO Specification forming part of Letters Patent No. 216,022,dated June 3,1879; application filed November 15, 1878.

To all whom it may concern:

Be it known that 1, JOHN T. OoNDoN, aresident of the city of NewOrleans, parish of Orleans, and State of Louisiana, have in vented acertain new and useful Improvement in Horse- Stable Unhitchers; and I dohereby declare the following to be a full, clear, and correctdes'cription of the same, reference being had to the annexed drawings,making a part of this specification. I This invention afiords a meansfor confining horses and other stock in stables or stalls in a mannerwhich will permit of their being released therefrom, either by hand orby electricity, the instant an alarm of fire or other cause may sorequire.

It consists in stretching a chain across the front of the stall orstable at aheight of about three feet from the floor thereof, the saidchain to have one of its ends permanently secured to one side of thestall or stable, as the case may be, and its other end provided with anopen ring or link, so that it may be secured to the opposite side of thestall or stable by I means of a sliding pin, the withdrawal of whichwill cause that end of the chain to drop, and thus free the animalspreviously confined thereby. I

Myinvention will, however, be much better understood by referring to theaccompanying drawings, whereon it is represented, at Figure 1, asapplied to a double stall, and at Fig. 2, to a single one.

A is a metallic frame, the face of which is provided with projectinglugs I) b, for the operation therein of a plunger, 0, upon which issecurely fitted a rubber or other bumper, as shown at d.

I In the double device, Fig. 1, the plunger is provided with a T-head,which consists of a flat plate, 0, (seen also in Fig. 3,) that isslipped over one end of the said plunger, and secured against the bumperthereof by means of jam= nuts, as shown at f. The aforesaid T-head isprovided, on each side of the plunger, with notches to receive the necksof a pair of locking-pins, h h, the ends of which are made to operate ina pair of raised lugs, t i, between which there is ample space for thereception of the links II, k, that form the drop ends of the chains L L,whose opposite ends are manently fastened to the outer walls 0 stalls,as shown at m m. I The locking-pins h h, by which, when 1', site, thechains are secured across the of the stalls, are constructed with knuljoints or a, in order that they may, whe so desired, be disconnectedfrom the T-* of the plunger. I I

The means employed for operatingthe d is as follows: The plunger G isconnectel shown at 0, with one end of a bell-crank, P, is pivoted at qto a plate, R, the latter h: raised lugs s s, in which is fitted asliding t, that is provided at one end with an ar I and at the oppositeend with an an groove, o, the former connected by a rod} with oneportion of the bell-crank, as s at x, and the latter affording a holdfor trigger y, by which it is designed to be I ated. The aforesaidtrigger is pivoted t plate R, as at z, and is connected with th s bymeans of an elastic sprin 1), causes it to partially rotate the momencatch at its upper end is released from. t. the trip-lever E, which isalso pivoted t plate, as shown at 1, and held in a locked, dition by anelastic spring, as shown at I For the purpose of driving forward theIing rod it when released by the springil the trigger, it is encircled bya spring, G end of which is permanently secured the as at h, while theother end has a be against the lug s, as shown. To spring the trigger ofthe device, the r end of the trip-lever E is moved in th} rectionindicated by the arrow-point 3, e by hand or by an electric wire, asshown In the single device the operating me ism is connected with theplunger there 0, in the same manner as that above indi for the doubleapparatus. I The plate A, with its mechanism, may cured in a verticalposition to the front o partition or wall, or in a horizontal posi asshown in the drawings, while the oper, mechanism can be secured to theside 0 said partition or wall, and thus present lit no obstructionwithin the stall or stable. Having described my invention, what I a,

as new, and desire to secure by Letters Patent, is

1. In combination with the plunger G, provided with bumper cl, jam-nutsf, and T-head c, the pins h'h, having knuckle-joints n 02', whereby theymay be folded outward from the T-head, and thus be freed from theoperations of the plunger, as set forth.

2. The plate R, combined with the operating mechanism, consisting of thebell-crank P,

connecting-rod -W, sliding rod t, springs G D F, trigger y, andtrip-lever E, all arranged and combined with the plunger 0, asdescribed, and for the purpose specified.

In testimony whereof I have hereunto signed my name.
